Can't the entry be shared for both platform_device_id and of_device_id?
Only one of them can be valid at the same time, right?

Ideally, all xxx_device_id look like

    struct xxx_device_id {
            ... /* bus-specific ID information */
            kernel_ulong_t driver_data;
    };

This may be formalized in some way, using a base class, but thay may
require reordering the fields, like:

    struct base_device_id {
            kernel_ulong_t driver_data;
            long id[0];
    };
